IOException - Cannot load file

Question

I have an app that shows GIF images. It all works fine if image is saved in drawable, and I access it like this

is=context.getResources().openRawResource(R.drawable.mygif);
movie = Movie.decodeStream(is);

But I need to download image from internet, so I'm saving it to CacheDir, that works fine. I tried the following to read it.

    try
    {
        is = new BufferedInputStream(new FileInputStream(new File(context.getCacheDir(), "mygif.gif")));
    }
    catch (FileNotFoundException e)
    {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    movie = Movie.decodeStream(is);

And this

movie = Movie.decodeFile(new File(context.getCacheDir(), "mygif.gif").getPath());

But no matter what, it ends with

java.io.IOException
at java.io.InputStream.reset(InputStream.java:218)
at android.graphics.Movie.decodeStream(Native Method)
at android.graphics.Movie.decodeTempStream(Movie.java:74)
at android.graphics.Movie.decodeFile(Movie.java:59)

or

java.io.IOException: Mark has been invalidated.
at java.io.BufferedInputStream.reset(BufferedInputStream.java:350)
at android.graphics.Movie.decodeStream(Native Method)

I think it's a very simple error, but I can't get over it. Manifest has:

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

Answer 1

suggestion:

1.try move the download location to another folder like: sdcard, or the app another folder except the cache.

2.when init the inputstream, try use: init with a buffer size

int buffersize = 16*1024;
InputStream  is = new BufferedInputStream(xxx,buffersize);

3.to check the file existed in your folder

update: change the code like this and dont use Movie.decodeFile

 InputStream is = null;
    try {
        is = new BufferedInputStream(new FileInputStream(new File(getCacheDir(), "mygif.gif")), 16 * 1024);
        is.mark(16 * 1024); 
    } catch (FileNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
movie = Movie.decodeStream(is);

no exception throw, and the movie is not null.

Also, although your code will throw the exception, the movie is also not null.

I know is a really old post, but I was having the same issue

Copying the InputStream to a byte array and calling Movie.decodeByteArray worked for me, even on Samsung Devices
